Vedclass · Answer

(D) In a sewage treatment plant,the primary effluent is passed into large aeration tanks. In these tanks,the effluent is constantly agitated mechanically and air is pumped into it. This allows vigorous growth of useful aerobic microbes into flocs (masses of bacteria associated with fungal filaments to form mesh-like structures). These flocs consume the major part of the organic matter in the effluent,which significantly reduces the $BOD$ (Biochemical Oxygen Demand) of the effluent. Therefore,the flocs are the active biological agents used in the aeration tank.
